Ok on my 91 all the power windows wont work FROM THEIR OWN SWITCH, but the driver door switches can control all the windows just fine.

Now I know your thinking the window lockout button but I tried it and it doesnt make a difference.

I was wondering if this is a known issue or if maybe my window lockout button has gone bad somehow.

Try removing the lockout switch ahd taking it apart and cleaning it,also lightly sand the contacts. I have three ford products and they have all done it,the smae goes for the window switches themselves.

yea, sounds like the lockout switch is bad... I think I have a complete set of switches avail in my parts car.

yeah i bypassed the lockout switch and all is well.

who needs child lockout anyway?

I have the switch assy avail if you want it... as far as I know, all works right on it.
